I'm using SPICE to simulate a circuit with a fair amount of complexity. The actual circuit has a light controlled resistor in it which is crucial for correct operation.
The light that controls the LCR is not simply on or off. The voltage drop will change dynamically and thus vary the resistance of the LCR. I need some way to simulate this in SPICE. I realize it's senseless to use light, but I can certainly use a voltage controlled resistor. Problem is that I don't have a library or part for that and I don't know where I can find one.
Does anyone know how I can simulate this - LCR or other method? The variable resistance is essential to the circuit operation.
I hope I find a great amount of help and expertise around here. Thanks!
